So any thoughts on the new Vertex 4s?

I know, it's OCZ, so the first thought for some might be to stay away... but I used a Vertex 3 for a long time without any issue, and I still have a couple of Vertex 2s running strong in various devices. They had a bad firmware update with their Agility drives (which were the cheapest of their three lines, so they were the ones most people bought), and I think that kind of gave the company an undeserved bad rap. Their Vertex offerings have been great for me. I just stay on top of the firmware updates, and always wait a couple days after one's been released so I can see if their are any reported problems.

Anyway... thoughts? According to Anandtech, the Vertex 4s blow everything else away at sequential and random writes, as well as "high workload" reads (like you'd see in an enterprise deployment), but they really drop the ball on the "typical computer load" reads. Usually, read speed is pretty important in choosing a drive, but the expectation is that the read thing will be cleared up in the next couple weeks with a firmware update. The cool part is that the drives right now are actually shipping with a full 1GB of on board DDR3 RAM for caching - which is insane.

The Everest 2 controller is flanked by a 512MB Micron DDR3-800 DRAM. Another 512MB chip exists on the flip side of the PCB bringing the total to a whopping 1GB of DDR3 memory on-board. OCZ makes no effort to hide the DRAM's purpose: Everest 2 will prefetch read requests from NAND into DRAM for quick servicing to the host. When serviced from DRAM, reads should complete as fast as the interface will allow it – in other words, the limit is the 6Gbps SATA interface, not the SSD.
